This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X450-40-S, with the same bore, stroke, output force, port and mounting, so it fits the same application. The MBLJ replacement upgrades to a riveted rolling-packed body and CMSG / DMSG / EMSG sensors (the MAL used CS1-M / DS1-M).
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-40-S
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-40-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 40 mm, giving a usable end-position window from 410 to 450 mm. This model is discontinued — the direct replacement is the MBLJ32X450-40-S.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-40-S
The AirTAC MALJ32X450-40-S is a discontinued adjustable-stroke, double-acting double-rod mini cylinder. It has a 32 mm bore, a 450 mm stroke, and a 40 mm rear adjuster, giving a usable end-position window of 410-450 mm. The direct replacement is the MBLJ32X450-40-S, matching the bore, stroke, force, G1/8 port, and mounting.
This SKU includes a -S magnet for position sensing; the legacy MALJ uses CS1-M or DS1-M switches, while the MBLJ upgrade uses CMSG, DMSG, or EMSG sensors. The MALJ features threaded covers, whereas the MBLJ uses a riveted rolling-packed body. Both generations use a fixed rubber bumper, meaning the adjustable stroke sets the end position but does not provide an air cushion. The adjuster is a travel stop, not a lock; it will not hold a load without live air pressure.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-40-S Technical Specifications
| Model | Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-40-S |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ32X450-40-S |
| Bore size | Ø32 mm |
| Stroke | 450 mm |
| Adjustable window | 410 – 450 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 500 mm |
The rear adjuster is a travel stop, not a lock — it sets the end position but does not hold the load without live air. No back-cover code and no SDB on adjustable-stroke. The MBLJ32X450-40-S carries the same ratings.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
MALJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative), lower than a single-rod MAL push of the same bore. The MBLJ32X450-40-S matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-40-S Is Used
Long-Stroke Pallet Squaring
Fine-tune the end position to square pallets on a 450 mm transfer line, using the bumper to absorb the 563 N impact at 0.7 MPa without external hard stops.
Film Lamination Roller
Adjust the rear stop by up to 40 mm to set precise nip pressure on a lamination roller, ensuring the 12 mm rod withstands the 346 N pull load without side-stress.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-40-S with MBLJ32X450-40-S
To replace the MALJ32X450-40-S, order the MBLJ32X450-40-S. Confirm the 32 mm bore, 450 mm stroke, 40 mm adjust code, G1/8 port, PT thread, and FA or LB mounting (there is no back-cover or SDB option). If upgrading the -S magnet, note the switch family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG. The adjuster is a stop, not a lock, so add an external lock for held loads.
At 450 mm stroke, the rod is highly susceptible to side-load bending, so ensure rigid guiding to prevent premature seal wear.
Upgrade checklist
- ✓ Order the MBLJ32X450-40-S (same bore/stroke/adjust)
- ✓ Same 410–450 mm adjustable window
- ✓ Adjuster is a stop, not a lock
- ✓ No back cover / SDB — plan an FA/LB mount
- ✓ Sensor: swap CS1-M/DS1-M → CMSG/DMSG/EMSG
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.1 – 1.0 MPa operating pressure.
- check The rear adjuster sets the end position — it is not a load lock.
- check No back-cover / SDB on adjustable-stroke — use FA / LB.
- check Front/rear covers are threaded — not for field disassembly.
- check For new builds, specify the MBLJ32X450-40-S instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-40-S FAQ
Yes, the MALJ32X450-40-S is discontinued. The direct replacement is the MBLJ32X450-40-S, matching the 32 mm bore, 450 mm stroke, 40 mm adjuster, force, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design and changes the -S magnet switches from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The 40 mm adjuster is a travel stop that lets you trim the end position, creating a usable stroke window of 410-450 mm. It is not a lock; it cannot hold a load without live air pressure.
